I found out that after cleaning the gravel over and over, it just grows back within a week or two...but if I leave it, it just gets to a certain point and stays there...so if you embrace the green lawn look, it isn't that bad...I hear ya! We're all destined for that phase lol. Just came out of it myself. Turf algae turned into cyano and then diatoms haha. Finally just stepping back out of it myself. Hope it clears up best it can!
But, if it starts to kill coral, or grow over something I like, it's out of there...
The rocks all seem fine though, that phase passed a few months ago...
